In addition to what has been said, the TOB should not touch the fingers until one inch of free play has been taken out by pushing the pedal forward. There is a spring under the floorboard that holds the pedal up and also hold the TOB off the fingers an 1/8" if everything is adjusted correctly. If the spring is broken, it'll alow the pedal to fall forward and contact the fingers, which will cause the pedal to "bounce" a bit as the engine spins.

I have a 48 cub with about 500 hrs total running time. all original,, gears are very quiet.. Some noise in a cub that has a lot of hours on it is ok. but when you feel the noise in the seat means excessive wear. Also who knows what the previous owners done to them inside over the years.
